Guys,

This has been GREAT! I tried recently to get to the same point as Clay has and have learned an awful lot from these messages. It looks like Clay and I have the same kind of block; ie. 427 SO Service Block. I was given all of the places to look, and like Clay, couldn't find anything like a casting number on the passenger side and only the casting numbers below #1, the "DIF" casting and the "352" on the front. All of his pictures match mine for locations. Like Clay's, mine is a hydralic block converted to solids. The dilemma now is what year is it and where can I find a part number, without disassembly, to determine? Anyone out there who can help?

Thanks.

John
